As shown, the teller it) is am'angcd adja cent to the calender roll 11 and is rotatably mounted on the. upper end portions of the.

are rotatably mounted the pressure rolls 3%,

which are pressed against the calender roll 12 by the weights on the rods 36 which are connected to bars 37 extending between the upper end. portions of the pairs of angular arms 33. On the upper part of the sup porting structure 23. are suitably mounted the stands 38between pairs of which ate connected the bars 39, which suitably carry rolls of lining material .10, and the pairs of pivoted arms ell which have bearing in their lower free end portions the stock sells 42.

From the foregoing description, the construction, manner ofusc and the advantages of the improved apparatus will be apparent to those skilled in the art. lt will be undcrstood that the mass of crudc'rubber material as may be placed to pass between the rolls 10 and 11 of the calender by which the matcrial is pressed into a comparatively thin sheet which passes around the lowei portion lie knives ll into sti'ios of material a l. The latter and the Waste strips are passed over the idler roller 19; the Waste strips being); dis-- carded, and the strips or plies 4 being downwardly from the roller 19 to the belt 17 which downwardly on the front portion the roll 12. lt will be seen that after laying}; down. on the belt ll'one strip oi" ply oil the length of the belt 1?, (Btl'lfilf d down on the l until the stool; is built up by the plies to he desired thickness. in passing around the roll 12 the plies of material are pressed by th pressure rolls 3%. After stock of the desiied thickness is built up from the plies, it is out transversely and one end portion of tliestock, together with an end portion ol' the lining material 40, are passed around the stock roll 42 and ate wound on the stock roll in consequence cl? rotation of the stoclt roll through the instt'mnentality of the mow ing' belt 17.
